Course detail

Machine Design - Mechanical Drives

FSI-6KT-AAcad. year: 2021/2022

The course provides an overview of machine components used to transmit power and rotary motion, such as gears, shaft clutches, brakes and flywheels. Attention is paid mainly to understanding their function and mastering the methodology used in their design. The course integrates knowledge gained in the theoretical subjects of the bachelor's degree in mechanical engineering, especially in materials science and mechanics.

Planned learning activities and teaching methods

Lectures, exercises, self-study.

Assesment methods and criteria linked to learning outcomes

The course is completed by taking an exam after the previous awarding of the credit.
The credit confirms that the student actively participated in the work during the semester and received at least 20 points out of a maximum of 40 points. The criterion of point evaluation is the degree of ability to solve assigned tasks correctly and independently.
The exam investigates the complex mastery of the subject matter defined in the course card and especially the ability to apply the acquired knowledge independently and creatively. The level of mastery of the issue is evaluated in the range of 0 to 60 points. The student must obtain at least 30 points out of maximum of 60 points.
The exam has a written and an oral part. The written part of the exam is mandatory for all students. It consists of two calculation tasks and one question. The oral part of the exam is voluntary.
